Amid fears of more violence, officials from various nations take steps to protect their citizens and interests in the Central African Republic.

France deployed 180 troops from Gabon to Bangui overnight to protect French citizens in the Central African Republic's capital, said Col. Thierry Burkhard, a spokesman for France's defense ministry.

U.S. President Barack Obama wrote a letter Saturday to Congress informing them that about 50 U.S. troops were sent to Chad on Thursday "to support the evacuation of U.S. embassy personnel and U.S. citizens from the Central African Republic."

Rebels were reported earlier last week to be about 190 miles from Bangui. But there's been a lull in rebel attacks in recent days.

Demonstrators in Bangui have urged foreign intervention to stop rebels from entering the city.

The unrest has prompted the United Nations to relocate dependents and nonessential staff from the country and the U.S. Embassy in Bangui to shut down operations. The U.S. State Department said Thursday -- the same day U.S. troops were sent to Chad -- its ambassador and diplomatic team left the capital, but that the United States is not cutting off diplomatic relations with the turbulent African nation.

Bozize specifically called on France -- which ruled his country, then as a colony known as Ubangi-Shari, until it gained independence in 1960 -- and the United States to help ensure "the rebels return home ... instead of destroying and killing Central Africans."

But Hollande said Thursday that his nation's troops are not there to "protect a regime," but instead protect French nationals and interests. France will not "interfere in the internal affairs of a country, in this case, CAR," Hollande said, adding, "That time is over."
